What do you see when you close your eyes and imagine the future? Do you picture a bleak, dark world ravaged by climate change and war? Or do you envision a brighter tomorrow, where science and technology have solved our biggest problems? Whichever vision of the future you choose to believe in, it's important to remember that it's just that – a vision. We can't let our dreams blind us to reality, and we need to be prepared for whatever comes our way. That's why it's so critical to stress test our visions of the future, to see if they hold up under pressure and if potential dangers are associated with them.
